[Fuyuno Mikan] My giant sister's next game [Full Color]

A playful and surreal sibling dynamic takes a massive scale when a giant sister decides to treat her tiny brother as her favorite toy. What begins as a sunny day in the park turns into an intense experience of physical absorption, as the brother ventures inside his sister's body to satisfy her cravings. As he moves deeper, the sensation becomes overwhelming, pushing through the vaginal canal toward the womb in a surprising display of scale-defying intimacy. The sister's expressions shift from teasingly dominant to breathless pleasure as her tiny brother's movements cause her to squirm uncontrollably, leading to a sudden, unexpected conclusion where he emerges on his own.
